Sometimes a project provides an opportunity to learn and is not destined to be finished. Sometimes it needs to just go away. Not all class projects are worthy of all the time they would take to make worthy of display. Just understand what you did incorrectly and use the skill in a new project without the same problems. At one time I bought a wedding ring quilt from someone who could not finish it. The colors were pretty and I was sure I could rescue it. I spent hours deconstructing, starching, etc. But the end was that I realized I couldn't do it because it had been poorly cut. It got dumped and I spent my quilting time doing something I could enjoy and be proud of. What a relief!
